delete() is a dummy entry in the manual so people looking for said function 
will be directed to unlink() which is the correct function to use.

delete() is undefined in php, that is why you can define your own function 
called delete().

unlink() can only remove/delete directories that are empty.

There's no error in the manual (with regards to this subject). Probably a 
misunderstanding on your part.

The delete() function as defined below is recursive and will automatically go 
inside non-empty directories and empty them first.

To summarise -- there is no delete() function in php, the delete() function 
you're using is a user-defined function and as such will do whatever you can 
make it do.
